If your court order does not require you to provide the father with notice or an itinerary, you do not have an obligation to give him this information. However, you should provide him with a phone number so that he can speak to the child while you are gone if the order permits telephone contact. If you have an attorney, you should ask him/her if there is any other protocol in your area as each county has their own protocol.
